The washer no longer cycles water during the wash cycle. I can here it hum, but the motor/pump does not run. I have inspected and cleaned the food chopper but that did not help. goes through the whole cycle, but just does not pump water for the wash phase. The empty (sump) pump woks fine.

You sound like you diagnosed it pretty good, so I think you can change the impeller. The biggest problem is making sure everything is lined up so it wont leak after its re-installed. I've never had much luck removing the old impeller without breaking it into pieces. just be careful not to mess up the shaft. If its an older machine, some Whirlpool/Kenmore can have the whole thing changed in one part. Its a little more $$ but it has the motor and all. And its easier and faster!! Also, your pressure problem may be related to the motor.

It's noisy If your dishwasher seems noisy, check these:

Water-inlet valve
Motor
Heater fan
Pump
Water-inlet valve An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.

Motor If it's the motor that's noisy, either of these may be the "culprit:"

• As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks (read about the main tub seal in the "It leaks" section, later).
  
  
• If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.
  
  

Heater fan If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.

Pump Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher.

To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.

if you have a torx 20, and torx 15 screw driver, you an remove the screws from the top plate of the wash motor, and underthere youll see another t15 screw converingthe "chopper" assy, sounds as if a seed, of chicken bone, perhaps apiece of glass hasgottne down there

Hi,

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...

SOURCE: The start/pause button beeps when

Hi

Ronald...the beep sound itself indicates an issue with the membrane switch (control panel) and it should be replaced. I believe that the pump and motor is fine as its just beeping and doing nothing else. Hope this helps...please post back for further assistance.
